Sealing ring for Demag AC80-1

The sealing ring, part number 340 443 99, is engineered to maintain the integrity of various systems within the Demag AC80-1 all-terrain crane. Its primary function is to prevent the leakage of hydraulic oil, lubricants, or coolants while simultaneously protecting internal components from the ingress of external contaminants such as dust, dirt, and moisture. This component is used at critical connection points where a hermetic barrier is required to ensure the efficient operation of the machine systems.

This sealing ring is compatible with the Demag AC80-1 crane. It is utilized in various assemblies including hydraulic cylinders, pumps, valves, transmissions, and axles, where it must withstand specific operating pressures and temperatures. By maintaining a proper seal, this component helps preserve operating pressure and ensures adequate lubrication for adjacent parts.

Sealing rings are used throughout heavy machinery to isolate fluids and gases within their respective circuits. They are positioned at joints and rotating shafts to contain pressurized media and prevent the entry of debris that could otherwise cause system contamination or mechanical wear. Regular inspection and replacement of these seals are standard practices in the maintenance of hydraulic and mechanical systems to prevent fluid loss and maintain operational efficiency.
